Homodotis falcata is a moth of the family Geometridae. It is endemic to New Zealand and is found in the southern part of the South Island. The larvae of this species feed on leaf litter and adults are on the wing for most months of the year. The forewings of this species can vary in depth of colour.
This species was first described in 1879 by Arthur Gardiner Butler and tentatively placed in the genus Larentia. Butler used a male specimen collected in Dunedin by F. W. Hutton. In 1883 Edward Meyrick, thinking he was describing a new species, named this species Eurydice cymosema. Meyrick synonymised that name in 1884. George Hudson discussed this species under the name Xanthorhoe falcata in his 1928 book The butterflies and moths of New Zealand. Hudson stated that Louis Beethoven Prout believed the holotype specimen to be a large dark form of the species Asaphodes rufescens. J. S. Dugdale agreed with Prout, pointing out in his 1988 publication, that the New Zealand Arthropod Collection holds specimens that have coloration ranging from dark, intermediate to light and as a result Dugdale synonymised Asaphodes rufescens with this species. The male holotype is held at the Natural... Wikipedia →

Possible
About 20% of wildlife watchers report a Homodotis falcata sighting in Rakiura National Park on a given day, based on 28 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 118 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Homodotis falcata in Rakiura National Park on a given day, against under 5% in April and August, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Homodotis falcata sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Rakiura National Park, in our data
Rakiura National Park is the only park on Wallace's Line with enough records to rate Homodotis falcata sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Geometridae
The closest relatives of the Homodotis falcata that you can see in Rakiura National Park (family Geometridae, Geometer Moths) are Forest Semilooper (about 40%), Common Forest Looper (about 30%) and Barred Pink Carpet (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Homodotis falcata is recorded against all the insects logged in Rakiura National Park (28 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
